[0002] A metal wire drawing machine is a piece of equipment used for surface treatment of metal materials. It is mainly used to draw metal materials into fine wires or threads to meet the needs of different fields.

[0003] The utility patent with prior art publication number CN216937733U discloses a metal wire drawing machine for bearing steel wire with controllable tension. By rotating the first screw and the second screw, the tension of the metal wire can be coarsely adjusted and finely adjusted, so that the tension of the metal wire can be precisely controlled.

[0004] However, during the use of the above-mentioned mechanism, the first and second screws do not have any auxiliary fixing parts. Therefore, when the wire drawing machine is working, the first and second screws may rotate due to machine vibration or external factors, which makes the tension adjustment more prone to change and inconvenient to use. Utility Model Content

[0005] The purpose of this invention is to provide a metal wire drawing machine with controllable tension to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a metal wire drawing machine with controllable tension, comprising a fixed frame, wherein a plurality of guide wheels are fixedly connected at equal intervals to the outer wall of the fixed frame, and a traction device is fixedly connected to the outer wall of the fixed frame;

[0008] The adjusting plate has an adjusting groove on the outer wall of the fixed frame, and the adjusting plate is slidably inserted into the inner cavity of the adjusting groove.

[0009] A snap-fit ​​assembly, which is disposed inside the adjustment plate, is used for multi-point positioning of the adjustment plate;

[0010] A fine-tuning component is disposed on the outer wall of the adjustment plate;

[0011] Tension wheel, which can be displaced on the adjustment plate by a fine-tuning component.

[0012] Preferably, the snap-fit ​​assembly includes:

[0013] The adjusting plate has a snap-fit ​​groove inside, and snap-fit ​​holes are provided on both sides of the inner wall of the adjusting groove. One end of each of the multiple snap-fit ​​rods is slidably inserted into the inner cavity of the snap-fit ​​groove, and the other end of each of the multiple snap-fit ​​rods is slidably inserted into the inner cavity of the snap-fit ​​hole.

[0015] Positioning rods, wherein multiple positioning rods are respectively fixedly connected to multiple pull rods, for use in multi-point positioning fine-tuning components;

[0016] A compression spring is located inside a positioning groove, and its two ends are respectively fixedly connected to multiple snap-fit ​​rods.

[0017] Preferably, a limit plate is rotatably connected to the top of the adjusting plate to limit the displacement distance of the pull rod.

[0018] Preferably, the fine-tuning component includes:

[0019] A sleeve, which is fixedly connected to the outer wall of the adjusting plate;

[0020] A telescopic rod, one end of which is slidably inserted into the inner cavity of a sleeve, and a tension wheel is rotatably mounted on the other end of the telescopic rod;

[0025] The technical effects and advantages of this utility model are as follows:

[0026] This invention utilizes a combination of an adjusting plate, a snap-fit ​​assembly, a fine-tuning assembly, and a tension wheel. The snap-fit ​​assembly not only allows for position adjustment of the adjusting plate (i.e., coarse adjustment of the tension wheel), but also enables fine-tuning of the tension wheel by the fine-tuning assembly, which then positions the assembly.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] This utility model provides, for example Figure 1-5 The metal wire drawing machine with controllable tension shown includes a fixed frame 1, a plurality of guide wheels 2 are fixedly connected at equal intervals to the outer wall of the fixed frame 1, and a traction device 3 is fixedly connected to the outer wall of the fixed frame 1.

[0035] Furthermore, a tension adjustment mechanism 4 is provided on the fixed frame 1. The tension adjustment mechanism 4 includes: an adjustment plate 41, a snap-fit ​​assembly 42, a fine-tuning assembly 43, and a tension wheel 44. An adjustment groove is provided on the outer wall of the fixed frame 1, and the adjustment plate 41 is slidably inserted into the inner cavity of the adjustment groove. The snap-fit ​​assembly 42 is located inside the adjustment plate 41 and is used for multi-point positioning of the adjustment plate 41. The fine-tuning assembly 43 is located on the outer wall of the adjustment plate 41. The tension wheel 44 can be displaced on the adjustment plate 41 through the fine-tuning assembly 43. The snap-fit ​​assembly 42 can not only adjust the position of the adjustment plate 41, i.e., make a coarse adjustment to the tension wheel 44, but also make a fine adjustment to the tension wheel 44 by the fine-tuning assembly 43 and then position the fine-tuning assembly 43. This can effectively prevent the drive rod 433 in the fine-tuning assembly 43 from rotating due to machine vibration when the wire drawing machine is working, thus preventing the tension wheel 44 from failing to adjust and ensuring that the tension wheel 44 can be used stably under machine vibration.

[0036] Specifically, the snap-fit ​​assembly 42 includes: snap-fit ​​rods 421, pull rods 422, positioning rods 423, and compression springs 424. The adjusting plate 41 has a snap-fit ​​groove inside, and snap-fit ​​holes are formed on both sides of the inner wall of the adjusting groove. One end of each snap-fit ​​rod 421 is slidably inserted into the inner cavity of the snap-fit ​​groove, and the other end of each snap-fit ​​rod 421 is slidably inserted into the inner cavity of the snap-fit ​​hole. Multiple pull rods 422 are fixedly connected to the multiple snap-fit ​​rods 421 respectively. The outer wall of the adjusting plate 41 has a pull groove, and the pull rods 422 are slidably inserted into the inner cavity of the pull groove. The springs are connected by pulling... Rod 422 can pull the snap-fit ​​rod 421 to move; multiple positioning rods 423 are fixedly connected to multiple pull rods 422 respectively, and are used for multi-point positioning fine adjustment component 43. When the pull rod 422 moves, it can drive the positioning rod 423 to move synchronously; compression spring 424 is located inside the positioning groove. The two ends of the compression spring 424 are fixedly connected to multiple snap-fit ​​rods 421 respectively. The compression spring 424 is always in a compressed state, so as to provide a stable elastic force to the multiple snap-fit ​​rods 421, so that the snap-fit ​​rods 421 can be stably snapped into the snap-fit ​​hole.

[0037] Furthermore, the top of the adjusting plate 41 is rotatably connected to a limiting plate 5, which is used to limit the displacement distance of the pull rod 422. When the limiting plate 5 is in contact with the adjusting plate 41, the distance that the pull rod 422 is pulled is just enough to make the positioning rod 423 disengage from the positioning hole, while the locking rod 421 will not disengage from the locking hole. When the limiting plate 5 is flipped up, the pull rod 422 can be pulled forcefully to make the locking rod 421 disengage from the locking hole.

[0038] Specifically, the fine-tuning component 43 includes: a sleeve 431, a telescopic rod 432, a drive rod 433, and a turntable 434. The sleeve 431 is fixedly connected to the outer wall of the adjusting plate 41. One end of the telescopic rod 432 is slidably inserted into the inner cavity of the sleeve 431, and the tension wheel 44 is rotatably installed on the other end of the telescopic rod 432. The drive rod 433 is rotatably disposed inside the sleeve 431, and the drive rod 433 and the telescopic rod 432 form a screw drive. The turntable 434 is fixedly connected to the top of the drive rod 433. The top of the turntable 434 has a groove, and the inner wall of the groove has multiple positioning holes at equal intervals. The positioning rod 423 is slidably inserted into the inner cavity of the positioning hole. The rotation of the turntable 434 can cause the drive rod 433 to drive the telescopic rod 432 to move vertically inside the sleeve 431, thereby driving the tension wheel 44 to make fine adjustments. This allows the metal wire drawing machine to achieve good tension adjustment during use. After the turntable 434 is adjusted, it can be positioned by the positioning rod 423, which can effectively prevent the drive rod 433 in the fine adjustment component 43 from rotating due to machine vibration during operation, thus preventing the tension wheel 44 from failing to adjust. This ensures that the tension wheel 44 can be used stably under machine vibration.

[0039] Furthermore, limit blocks 6 are fixedly connected to both sides of the telescopic rod 432, and limit grooves are opened on both sides of the inner wall of the sleeve 431. The limit blocks 6 are slidably inserted into the inner cavity of the limit grooves. The limit blocks 6 play a role in limiting the movement of the telescopic rod 432, so that when the drive rod 433 rotates, the telescopic rod 432 can only move vertically along the limit grooves.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
